Skylights in Palm Beach County: Installation, Leak Prevention, and Replacement Guide

Skylights bring natural light into Palm Beach County homes, reduce daytime lighting costs, and create an open, airy feeling that is particularly appealing in South Florida's outdoor-oriented lifestyle. But skylights also represent one of the most significant potential leak points in any residential roofing system. Understanding proper skylight installation, common failure modes, and maintenance requirements will help Palm Beach County homeowners enjoy the benefits of skylights without the headaches.

Skylight Installation in Palm Beach County: Critical Requirements

In Palm Beach County's hurricane zone, skylight installation has specific code requirements that go beyond those in most other markets. Florida Building Code requires skylights to have impact-resistant glazing or be protected by approved impact-resistant covers (hurricane shutters for skylights). This is particularly important because skylight failure during a hurricane can cause catastrophic wind and water damage to the interior — the opening created by a failed skylight allows wind pressurization of the attic that can result in complete roof failure.

Why Skylights Leak: The Most Common Failure Modes

• Flashing failure: The leading cause of skylight leaks. The flashing that seals the skylight curb to the surrounding roof surface can fail due to improper installation, sealant degradation, corrosion, or thermal cycling fatigue.

• Condensation: Skylights can accumulate condensation on the underside of the glazing, particularly in air-conditioned homes where the temperature differential between indoor and outdoor air is large. This appears as 'leaking' but is actually moisture condensation, not water intrusion.

• Glazing seal failure: The seal between the glazing unit and the skylight frame can deteriorate over time, allowing water infiltration into the skylight assembly.

• Curb damage: The curb (the raised frame that supports the skylight above the roof surface) can be damaged by debris impact, storm events, or deterioration over time.

Skylight Replacement: When Is It Time?

Skylight lifespans in Palm Beach County are typically shorter than in less demanding climates. UV degradation, thermal cycling, and hurricane exposure combine to shorten glazing life. Signs that skylights may need replacement include: yellowing or clouding of the glazing (which reduces light transmission and indicates UV degradation); persistent leaking that cannot be resolved with flashing repair; damaged or deteriorated frame seals; and any impact damage to the glazing from debris. When replacing a roof, Ranger Roofing typically recommends skylight evaluation and replacement if they are more than 15-20 years old.

Frequently Asked Questions: Skylights and Roofing

Should I replace my skylights when I replace my roof?

In most cases, yes — particularly if the skylights are more than 15 years old. Replacing skylights during a roof replacement avoids the cost of opening up the new roof to replace them separately later. It also ensures the new flashing integration is done as part of the primary roofing system installation, providing the best possible waterproofing. Ranger Roofing assesses skylight condition during every roof inspection and replacement project.
